Objective:To develop a method of rapid detection for Dalbergiae Odoriferae Lignum and related Chinese traditional medicine by portable gas chromatography. Methods:Retention index of characteristic peaks in Dalbergiae Odoriferae Lignum was used to analyse sample. DB-5Scapillary column(1m×0.25μm×0.35mm) was used,surface acoustic wave detectorSwas used with temperature of 60℃,Helium gas was used as the carrier gas with flow rate of 3.0 mL.min<sub>-1</sub>,the valve temperature was 165℃, theSsample inletStemperature was 200℃,the concentrated tube temperature was 250℃,the initial temperature of column was 40 ℃,then increased to 200℃ at a rate of 10℃.s<sub>-1</sub>,the injection time was 10s.Results:The main characteristic peaks of Dalbergiae Odoriferae Lignum were well separated in 1 min.,the method was specific,durable and accurate to identify Dalbergiae Odoriferae Lignum and related Chinese traditional medicine.Conclusion:The portable gas chromatography was simple,rapid and sensitive,it can be used for rapid detection in Dalbergiae Odoriferae Lignum and related Chinese traditional medicine. |
